When categorizing plate heat exchangers, they can be divided into different types based on various attributes. Firstly, if categorized by the heat exchange area per unit space, plate heat exchangers are actually classified as compact heat exchangers. Of course, this classification is not specific to the internal structure of plate heat exchangers but applies to the entire heat exchanger industry. For instance, when compared to shell-and-tube heat exchangers.

In terms of the process and application of heat exchangers, they are mainly categorized into: plate heaters, plate coolers, plate condensers, and plate preheaters.

Based on the combined process, it is divided into: single-pass plate heat exchangers and multi-pass plate heat exchangers.

Certainly, we can also categorize them based on the flow direction of the two media: plate heat exchangers with parallel flow, counterflow plate heat exchangers, and crossflow plate heat exchangers.

If categorized by the size of the alkaline washing of the channels, they can be divided into regular gap plate heat exchangers and wide gap plate heat exchangers.

Another way to categorize products is by whether they are complete sets. This allows for the division into standalone plate heat exchangers and plate heat exchanger units.
